The number of citizens is doubled.

The Coelian mount is added to the city, and in order that it might be inhabited more populously, Tullus selects that situation for his palace and there took up his abode.

The leading persons among the Albans he enrols among the patricians, that that branch of the state also might increase, the Julii, Servilii, Quinctii, Geganii, Curiatii, Cloelii; and as a consecrated place of meeting for the order augmented by him he built a senate-house, which was called Hostilia even down to the age of our fathers.

And that every rank might acquire some additional strength from the new people, he formed ten troops of horsemen from among the Albans: he likewise recruited the old, and raised new legions from the same source.

Confiding in this increase of strength, Tullus declares war against the Sabines, a nation at that time the most powerful, next to the Etrurians, in men and in arms.
Injuries had been done on both sides, and restitution demanded in vain.
Tullus complained that some Roman merchants had been seized in an open market near the temple of Feronia; the Sabines, that some of their people had taken refuge in the asylum, and were detained at Rome.
